Fluorescein diphosphate
WebInhibition of fluorescein-Fbg binding by underivatized Fbg. Fluorescein-Fbg was diluted with increasing amounts of under- ivatized fibrinogen, and these mixtures were then analyzed for bind- ing to ADP-stimulated platelets. The total level of Fbg in each assay was held constant at 1 mgiml. After activation and binding for 10 min WebJun 1, 2003 · Many assays for protein tyrosine phosphatases (PTPs) rely on colorimetric substrates or more recently developed fluorescent substrates. Enzyme activity is measured but no assessment of specific activity is made, which is important since these enzymes can exist in an enzymatically inactive form.
